P1406 2012 Ford Fusion Code - DPFE Sensor Circuit Downstream Hose
Quick Answer
The P1406 diagnostic trouble code (DTC) for a 2012 Ford Fusion specifically refers to an issue with the Differential Pressure Feedback Electronic (DPFE) sensor circuit downstream hose. Common causes include Damaged Hose: The downstream hose connecting the EGR system to the DPFE sensor may be damaged or cracked, causing a leak in the system, Faulty DPFE Sensor: The DPFE sensor itself may be faulty, providing incorrect pressure readings to the vehicle's engine control module, Wiring Issues: There could be a wiring problem in the circuit, such as a short or open circuit, preventing proper communication between the sensor and the engine control module. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P1406 2012 Ford Fusion Description
The P1406 diagnostic trouble code (DTC) for a 2012 Ford Fusion specifically refers to an issue with the Differential Pressure Feedback Electronic (DPFE) sensor circuit downstream hose. The DPFE sensor is a crucial component in the vehicle's exhaust gas recirculation (EGR) system, which helps reduce emissions and improve fuel efficiency. The downstream hose is responsible for transmitting pressure readings from the EGR system to the DPFE sensor.
Common Causes of P1406 2012 Ford Fusion
- Damaged Hose: The downstream hose connecting the EGR system to the DPFE sensor may be damaged or cracked, causing a leak in the system.
- Faulty DPFE Sensor: The DPFE sensor itself may be faulty, providing incorrect pressure readings to the vehicle's engine control module.
- Wiring Issues: There could be a wiring problem in the circuit, such as a short or open circuit, preventing proper communication between the sensor and the engine control module.
- Clogged EGR System: A clogged EGR system can also trigger the P1406 code, as it affects the flow of exhaust gases and pressure readings.
Symptoms of P1406 2012 Ford Fusion
- Check Engine Light: The most common symptom associated with the P1406 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Rough Idle: The engine may experience rough idling or hesitation during acceleration due to the EGR system not functioning correctly.
- Decreased Fuel Efficiency: A faulty DPFE sensor circuit downstream hose can lead to decreased fuel efficiency as the engine may not be operating at optimal levels.
- Increased Emissions: The vehicle may produce higher emissions than usual, potentially leading to a failed emissions test.
How to Fix P1406 2012 Ford Fusion
- Diagnose the Issue: Use a scan tool to retrieve the trouble codes and perform a thorough inspection of the DPFE sensor circuit downstream hose, sensor, and wiring.
- Replace Downstream Hose: If the downstream hose is damaged, cracked, or leaking, replace it with a new one to ensure proper pressure readings.
- Replace DPFE Sensor: If the DPFE sensor is faulty, replace it with a new sensor to accurately measure pressure in the EGR system.
- Check Wiring: Inspect the wiring for any damage or corrosion, and repair or replace any faulty wiring connections.
- Clear Codes and Test Drive: After completing the repairs, clear the trouble codes from the vehicle's memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1406 2012 Ford Fusion
The typical repair costs for addressing a P1406 code on a 2012 Ford Fusion can range from $100 to $300, including parts and labor. However, specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's advisable to check local rates for a more precise estimate. Keep in mind that rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less.
